To listen to some people on here you'd think it was a major problem that there's no user manual with this thing. Here, I'll write you one.Install the batteries (which were NOT included) and the unit lights up. The small button on the left turns on the light for a few seconds and holding it down will lock the light ON. There is a 4-way directional pad in the middle with a SET button in the center. Use the left and right buttons to toggle the mode between DELAY (how long the unit waits to fire the shutter), LONG (how long a long, or bulb, exposure will last), INTVL (the time between "time lapse" shots, minimum is 00:00'01") and N (number of shots the unit will take before stopping. "- -" is infinite shots, 1 is normal). The musical symbol allows you to toggle the beeps on and off.To change a setting, you press the SET button in one of the modes, then use the directional pad left and right to highlight the time or number you want to change (HH:MM'SS"), then press up and down to set the time or number. Press SET to lock the setting.Another small button labeled TIMER START/STOP starts the timer/bulb/interval, etc countdown and function,and takes pictures. An LED on the unit lights green when autofocusing, and red when the shutter is released. You can have ANY combination of settings. For example, a time delayed shot that holds the shutter open for 10 seconds, once every 5 minutes, for 30 exposures. If you simply want to use the unit as a remote shutter release, you don't even need batteries. Just press the big button in the middle of the unit. It even has half-presses for autofocus. The big button will not use the timer features, however, just the small one on the upper right. There's even a lock on the big button for long exposures.There is no on/off switch, which is baffling. I got around this by putting a piece of waxed paper between one of the batteries and the contacts so that I could leave them in the unit. To turn it on, I simply pull out the paper. It's a little more time to reinstall it when you're done, but that slower part comes after your pictures are taken and you don't have to fool with batteries while trying to set up a shot, just yank out the tab.This remote works with my Rebel XT perfectly fine. I'm very well satisfied for the money.EDIT: After the commenter below piqued my interest about an auto shutoff, I gave an off the hip response. I decided later to see just how long this unit would last on the batteries if you just left it on. Mine's been on now for days, maybe a couple weeks, and shows no sign of slowing. I guess you don't need an on/off switch. It appears to consume little to no battery when it's not actively in use, probably less than a wristwatch would since it's really just an LCD display.

I have had my eye on one of these timers for a while. I wanted to shoot some night skies and some time-lapse projects and you need an Intervalometer to do it right. This one from Neewer is just perfect. This model for Canon comes with 2 different ends that connect to whichever Canon model you own. I made sure that this one was compatible with my new Rebel T7i. A word of warning, that this little gem of hardware needs to be properly studied and understood BEFORE you go outside into the pitch blackness of night! Also I would advise the use of another small flashlight, or headband mounted light that allows you to be hands free to set the settings on the timer. Reading the manual is highly recommended and a little practice with it connected to your camera will all only help towards getting the kind of shots you expect and want. The cord on this timer is suitably long enough for you to easily connect to the camera and while pressing the button to activate the shutter, not transfer any vibration back to the camera. I also read another comment about why there is even a sliding locking collar on the main release button, well that is so you can lock the shutter in the open position to use in bulb mode. If you wanted to hold the shutter open for 5 seconds, you lock the slider into position and count 5 seconds and then release it. You can also just hold the main button down for the same effect and release after. This timer really comes into it's own when used for time-lapse shots. It can be set to open and close your shutter many times over a designated period of time. It's all in the manual so don't skip it. I was a little disappointed with the built-in light. It does not stay on very long and gets a little frustrating when trying to input settings. Hence the advice for a flashlight. It's built very well, it takes 2 AAA batteries and I have read about those lasting for many months of use, as yet I cannot attest to that. You'd be crazy to even consider the Canon branded version of this with it's $60+ price tag! This was $14.99 and I am very happy with it's use so far. I'm a serious amateur photographer, if you fall into this category too, do yourself a favor and get one.

Works great with my Canon 60DAs soon as the weather warms up. I'm going to try to do star trails.Also time laps of plants growing

Came in the mail at a reasonable speed (for the slow speed that I paid for). Overall, I really enjoy this product, especially for the price I paid for it. The HUD light up display is really handy when you're shooting in low lighting condition. It didn't come with directions but it took me less than 5 minutes to figure it out. If you're have a basic understanding of time lapse photography or even just photography you'll figure out how to use this product. I really love having 2 adapters for different camera types, but I've used only 1 of them so far for my Canon 10D. I've already taken this with me on 3 night shoots and it's performed very well. It also has a manual shutter release button for when you need the immediacy of releasing it but want a steady/no camera shake shot.My only complaint is that you have to remove the batteries for it to completely turn off, otherwise it'll stay on until it drains the AAA's. There was one instance where it was one of those 5 minute windows in the day when the clouds and sky we're beautiful and I ran to grab my camera and release timer (I was doing slow shutter stuff and I'm super OCD about camera shake). It wasn't until after I had set up the camera that I realized that my shutter release trigger was missing a battery from the last time I had removed it to turn off the product. I'll need to figure out a better workflow for removing/keeping track of my batteries, and it's a small inconvenience (reason for 4 stars). For the price I paid, I'm very happy with the product and would recommend it to anyone shopping on a budget.
